Day 1 Fire Weather Outlook
NWS Storm Prediction Center Norman OK
0138 AM CDT Sat Jul 26 2025

Valid 261200Z - 271200Z

...Synopsis...
A broad upper trough will overspread much of the western U.S. while
upper ridging persists east of the Rockies today. Multiple embedded
mid-level impulses will traverse the northern Great Basin into the
northern Rockies during the afternoon, encouraging dry and breezy
conditions across parts of the Great Basin into the Four Corners
region, as well as thunderstorm development into the Pacific
Northwest.

By afternoon peak heating, southwesterly sustained surface winds
will reach 15-25 mph as RH dips to 10-20 percent across the eastern
Great Basin/Four Corners. Elevated highlights have been maintained
given the presence of dry fuels. Farther to the northwest, from
Northeast California to the Idaho/Montana border, adequate mid-level
moisture and deep-layer ascent will support isolated to scattered
thunderstorm development atop a dry boundary layer. High-based
thunderstorms will produce a mix of wet and dry strikes atop
receptive fuels, warranting the continuation of isolated dry
thunderstorm highlights.
